A controversial new paper questions whether the interstellar object 3I/ATLAS is a potentially dangerous alien probe, similar to claims made about 'Oumuamua. But experts have called it "nonsense".

A newly unveiled astronaut photo shows a "gigantic jet" shooting upward from a thunderstorm above Louisiana in November 2024.

Black holes that have been obscured by clouds of dust still emit infrared light, enabling astronomers to spot them for the very first time

Scientists say AI has crossed a critical 'red line' after demonstrating how two popular large language models could clone themselves.

Images captured by NASA's Solar Dynamics Observatory have revealed that "coronal loops" give off subtle flashes of ultraviolet light before a solar flare, which could act as an early warning system for dangerous space weather.

A new way of measuring structures deep inside Earth has highlighted numerous previously unknown blobs within our planet's mantle. These anomalies are surprisingly similar to sunken chunks of Earth's crust but appear in seemingly impossible places.

A pair of massive thunderstorms have been spotted swirling in Jupiter's "South Equatorial Belt" and are likely unleashing massive bolts of green lightning. Some experts think the pale clouds could end up altering the rusty band's color — and potentially even making it "disappear."

A "bizarre" E-shaped aurora was recently photographed dancing in the sky above Alaska. The unusual light show was caused by rare black auroras, a.k.a. anti-auroras, which catapult charged particles from the sun back out of Earth's atmosphere and into space.

Space weather experts warn that solar activity will persist or even increase after solar maximum has ended and we enter a phase of the solar cycle dubbed the "battle zone."

Curiosity has just finished the latest leg of its 12-year Mars mission and will now set out to explore miles of web-like surface features left behind by ancient water on the Red Planet. The zig-zagging rocks could also provide clues about whether Mars once harbored extraterrestrial life.

A student-led project comparing satellite images of the Arctic has discovered that a small Russian island has recently vanished after "completely melting" away.

The cryovolcanic "centaur" comet 29P/Schwassmann-Wachmann has erupted four times in less than 48 hours, becoming unusually bright in the process. It is the most powerful outburst from the city-size oddball in more than three years.

A recent satellite image captured the reemergence of a unique, UFO-like cloud, known as the "Taieri Pet," which appears above New Zealand's South Island when conditions are just right.

A new video shows how Earth's magnetic field weakened and warped before temporarily flipping during a recent "polar reversal event."

Newfound comet C/2024 S1 will light up Earth's skies in late October before a super close slingshot around the sun.

Newly released images of Mars reveal a "smiley" salt deposit on the Red Planet's surface. A related study suggests that similar deposits, which were left behind from ancient lakes, may be a good place to look for signs of former life on Mars.

New studies, which utilized AI to monitor the effects of climate change on Earth's spin, have shown that our days are getting increasingly longer and that our planet will get more wobbly in the future. These changes could have major implications for humanity's future.

Some experts believe that the solar system's hypothetical ninth planet could be just a few years away from being discovered. If this is the case, how long would it take for humans to send probes to the elusive world?

Astronomers have been scouring the outer solar system for signs of a hypothetical ninth planet for almost a decade, without success. However, we may finally be on the cusp of finding it, experts say.

Alaska's melting permafrost is dumping toxic metals into the state's rivers, turning them bright orange and making the water highly acidic. The contaminated rivers are so vibrant they can be seen from space, and the problem is likely to get much worse in the future.

A tiny, previously undisclosed lunar rover has been spotted strapped to the side of China's moon-bound Chang'e 6 lander in newly released pre-launch photos. The true purpose of the rover, which is scheduled to land on the moon's far side, remains a mystery.

Several media outlets have incorrectly claimed that explosive solar flares were spotted during the April 8 total solar eclipse. But there were no flares during totality, so what did people see?

A new study warns that 5,000 meteorites could be sinking beneath Antarctica's icy surface every year as a result of climate change, depriving scientists of vital information about our solar system.

New images show a glowing "dashed" line in the night sky above Arizona after part of a SpaceX Falcon 9 rocket fell back to Earth following a double-header launch.

Earlier this month, a sudden atmospheric warming event caused the Arctic's polar vortex to reverse its trajectory. The swirling ring of cold air is now spinning in the wrong direction, which has triggered a record-breaking "ozone spike" and could impact global weather patterns.
